When I first moved to Spain, opening a bank account usually meant choosing between major banks like Santander, BBVA, or CaixaBank, mainly for the convenience of their extensive branch and ATM networks. However, after chatting with a Spanish friend recently, I learned about a unique type of bank here, known as ‘ethical banking’ or ‘Banca Ética’.
Simply put, these banks don’t operate with the sole objective of maximizing shareholder profits. They commit to investing depositors’ money into projects with positive social, cultural, or environmental impacts, such as renewable energy, organic farming, social housing, and fair trade. The entire investment process is highly transparent; you can even check on their website to see the specific projects your money has been loaned to. I find this concept incredibly cool. It feels like my savings are no longer just cold, hard numbers but are actively contributing to creating a better world.

Mainstream Ethical Banks in Spain
From my research, there are two main ethical banks in Spain. Both are part of the broader European ethical finance network and are very well-regulated.
Fiare Banca Ética
This is one I’ve been following closely, especially in relation to banks for Spain’s non-lucrative residency. It’s the Spanish branch of Italy’s Banca Popolare Etica and is fully dedicated to ethical finance. A key feature is its close collaboration with numerous social organizations, giving it a strong community feel. When you open an account, you can become a ‘socio’ (member), allowing you to participate in the bank’s decision-making and truly embrace the concept of cooperative finance. The annual fees are relatively affordable, but physical branches are very limited, with most services handled online or through partner locations.
Triodos Bank
Some of you may have heard of this one. Originating in the Netherlands, it’s one of the global pioneers in ethical banking, with operations in several European countries. Triodos Bank is larger than Fiare and offers a wider range of financial products, including personal accounts, business loans, and investment funds. Their website and app are well-designed, providing a good user experience. However, it’s worth noting that since 2021, Triodos Bank has been charging a maintenance fee for personal current accounts, so it’s best to check their official website for the latest rates.
| Feature Comparison | Fiare Banca Ética | Triodos Bank |
| Origin | Italy | Netherlands |
| Scale | Smaller, strong community focus | Larger, international |
| Core Philosophy | Cooperative finance, member participation | Sustainable development, investment transparency |
| Main Services | Personal savings, social project loans | Personal/business finance, investment funds |
| Fees | Lower annual fees | Account maintenance fees apply |
Choosing an ethical bank might mean giving up some of the conveniences of traditional large banks, like ubiquitous branches and ATMs. But what you gain is a sense of fulfillment, knowing your money is being used for socially beneficial purposes. It’s more of a choice based on values. I’m curious if anyone in the community has used these types of banks. Feel free to share your experiences!
